A Korean Air spokesman confirmed the incident aboard the flight from Hanoi to Seoul and that photos on Marx’s Facebook page were shot during the flight. Cho Hyun Mook said the matter was under investigation and that it appears that crew members responded in accordance with airline policies.

Marx posted a later update saying he and Fuentes were home safe and saying he wasn’t a “big ‘hero'” but “just did what I would hope anyone would do in the same situation.”

Citing Incheon police, the Yonhap News Agency reported that the passenger was a 34-year-old South Korean man who became drunk after having two and a half glasses of hard liquor on the flight. Incheon police officials could not be reached for comment.
